I te mea ko te waahanga mahi o te punaha whakahaere uru, ko te raka hiko e hono tika ana ki te pumau o te punaha katoa.E ai ki nga tatau rereke rereke, ka wehea nga raka hiko ki nga momo e wha: raka raka hiko, raka autō, raka anode me raka cathode.
1. Whakawetohia me te raka moti hiko whakatuwhera kuaha
2. Whakaweto me te raka moti hiko kati-tatau
3. Ko te raka motika hiko o te matua miihini whakauru
A, momo kuaha tuwhera whakakaha
B, momo kuaha kati
4. Ko te tatau karaehe anga karekau he raka moti hiko
E ai ki te maha o nga matua
1. Mahi Paerewa: 2-waea momo waea whero (+12V), waea pango (GND)
2. Ki te raka tohu tohu urupare
4-waea momo 2 waea hiko, 2 waea tohu (NC/COM)
5-waea momo 2 taura hiko, 3 waea tohu (NC/NO/COM)
3. Me te tohu tohu raka me te tohu tohu tohu tatau
6-waea momo 2 taura hiko, 2 tohu tohu raka, 2 tohu tohu tatau
8-waea momo 2 taura hiko, 3 tohu tohu raka, 3 tohu tohu tatau
